My invention relates to magazine pencilsv 12-'12 of Figure 11.

f, and-refers particularly to a device in which ,any predetermined crayonof a plurality carried by the device may be presented for use.

In many kinds; of" clerical accounting and check-ing work it is necessary to employ a marking of each colorpossessing a certain `designatedmeaning;

It is evident that a single, compact, easily workable pencil carrying a plurality oil crayons' has many advantages over a plurality of pencils, each one carrying but a single crayon.

The device of my invention is a vmagazine pencil, or crayon carrier, capable Vof containinga plurality .of crayons, each of which is readily exposed for use, the device having mechanism.particularly adapted for expos ring any desired length of crayon to compensate fork wear, and for other valuableand practical results, all ofwliicliwill be evident upon a consideration of' this specification and the accompanying drawings. v

ln the accompanying drawings, illustrating modified forms of the device of my invention, similar` parts are designated by'similar numerals. 5

Figure 12 is a cross-section through the line The particular form of ythe device' or my invention shown in the. accompanying drawings lcompri'ses an outerv tubular member or,V vcasing 11;, slidable withinwliich is an inner tubular member 12 extended `into thenozzle 213 having an opening 14 therein.` The upper portionvoil the tube 12 has an internally of 'the shown `device being hexagoiito accom- Fixedly attached to 'the inner-.1 face of' the casing l1, isa strip of metal 16 having a plurality of parallelgroovesV 17 17.

The inner 'tube 12 has a plurality of parallel grooves 18, 18 corresponding in number andpitch to the grooves 17, 17 ofl the outer casing 11.,y The tube 12 has a .longitudinal opening 19 so shaped andpositioned as to re- -ceive Vthe strip 16 of the outer tube11.

'A mark 39 is placed on tlietubev 12 and. the lower edge 40 of casing 11. registers therewith when adjusting described later. p Y

-Within the inner tube 12, isa Vcrayonholder carrier comprising the bar 20wliich is pointed at its lower end 21,.'whicli is ca- ,position of crayons as f pable of partial placement within the nozzle 13. A fixedflange 22 carried by the bar 20, l

of the casing .11 or'fla'ngefi23. It will thus :be seen-'that thebar 2O andthe outer casing 11 willmove .togethervertically and that the bar 20fmay be revolvedindependently oi the outer casing 11. 5

The. bar 2O has a pluralityof cliannels24,

I 24, 24- tQ receive crayon holders described later. Intermedi ate between the channels 24,l 24, 24" are flat springs 25 so attachedth'at when compressed `against the bar 20, they will be Hush with the outer intermediate portions 26 of the bar'20.,` The bar 2O1 is slidable vertically through the polygons'l'iapedtopl` of' the inner tube'12,b1"i`t not revolubletlierein, unless the crayon carrier and the outer casing 11 are moved along the inner' tube 12 until the top 15 of the inner tube 12 is in alignment with the rounded portion 27 oi`l the bar 20, as indicated in dotted lines 15 in Figure 5.

The ilange 22 has a plurality ot recesses 28, 28, 28 corresponding in number and position to the intermediate sections 26, 26, 26 between channels 24, 24, 24, these recesses allow strip 16 of casing 11 to pass flange 22 when assembling device.

Each crayon holder 29 comprises an upper member 30, having a central slit 31, which acts as a spring, and a plurality ot teeth 32, 32 capable of placement within the grooves 17, 17 ot' strip 16 and the grooves 18, 18 of the inner tube 12. The portion 29 of each crayon holder is extended into a split tubular member 33, 33, having a slit 34 and pointed ends, in order to hold the crayon 35 by spring frictional contact.

The teeth 32, 32 have their ends slightly rounded to insure smooth action. As shown in Figure 10, the grooves 32, 32 of the crayon holders and grooves 17, 17 of strip 16 are of the same shape and pitch. The grooves 18, 18 of the inner tube 12 and the teeth 32, 32 of the crayon holders are of the same pitch but the former are not quite as deep asthe latter. This construction is employed to permit a slight clearance in order that the crayon holders will move easily within the inner shell 12 when the bar 20 is revolved.

The grooves 18 at their ends nearest the slot 19 are tapered to the same depth as strip grooves 17 so that the crayon holder teeth 32, 32 will slide easily from engagement with one set of grooves to the other.

The upper portions of the crayon holders are shaped to lit slidably in channels 24 of the bar 20.

The inner tube 12 has openings 36, 36 in the upper portion, so that when it is desired to remove the bar 20, the flat springs 25, 25 may be compressed by passing wires, or other suitable means, through these holes enabling the springs 25, 25 to pass the under edge of the polygon shaped opening 15.

The inner tube 12 has a. shallow recess 37 in the upper portion opposite the slot 19 and a. similar shallow recess 38 is cut near the top of the strip 16. The object of these recesses is that as the bar 20 is revolved, the top of one ot' the springs 25 will engage one of these recesses alternately to assist in determining the position of said bar, but not deeply enough to prevent the rotary movement of the bar.

To assemble the device, the bar 20 is inserted in the inner tube 12 through an opening of the polygon shaped top 15 until the rotatable part 27 of the bar 20 is in line with the said top opening, as shown in dotted lines 15', in Figure 5. The bar 20 is then revolved until one of the channels 24 is in line with the slot 19 of the inner tube 12. A crayon holder with crayon is then placed in the channel. rlrhe bar is revolved until another channel is aligned with the slot and another crayon holder inserted. This is repeated for the third channel. The bar 20 is then revolved until an intern'iediate section 26 of the bar is in line with slot 19 and the bar 20 pushed all the way down within the inner tube until the flange 22 rests on the top 15 of the tube 12, the outer casing 11 is then pushed all the way down on inner tube 12 until the iange 23 of the outer casing 1l rests on the tlange 22 of the bar 20 and the cap 24 is then screwed into position.

In the operation and use of the invention the nozzle end is grasped in one hand and the casing 11 with bar 2O is pulled upward by grasping the cap 24 with the other hand, the upward movement o1 these parts is checked by the top ot iiat springs 25 coming in contact with the under edge of regular polygon shaped top opening of inner tube 12, as shown in dotted lines 15 in Figure 5. Then the bar 2O is rotated by means ot the cap 24 until the crayon selected to be used is opposite the slot 19 and directly over the opening 14 ot' nozzle 13 crayon will be visible through part of the slot 19, uncovered by the outer casing in this position, also the engagement of the recess 37 by one olE the flat springs 25 will indicate correct position. Then the outer casing 11 is moved downward into position shown in Figure 1 of drawings, causing the crayon holder with its teeth 32 engaged with grooves 17 of strip 16 to slide downward, thus projecting the end ot crayon through the nozzle opening` readv for use.

To select another crayon :for use, repeat the operation, rotating the bar 2O until the desired crayon is opposite the slot 19 ot inner tube 12.

When device is not in use, the above described operation is repeated, except that bar 20 is rotated to bring an intermediate section 26 of bar 20 opposite the slot 19, when the top of one of the ilat springs 25 will engage the recess 38 at top of strip 16. VJhen outer casing is then pushed down7 no crayons will be projected through nozzle opening, as no crayon holders are engaged with strip 16.

The amount ot' crayon projected through nozzle opening is regulated by shifting the crayon holder up or down to engage its teeth with a higher or lower set of grooves 17 or 18. For this purpose a mark 39 is provided on inner tube 12. To increase the length of projection of crayon, the outer casing 11 with crayon holder and crayon to be adjusted having its teeth 32 engaged with strip 16 is set with lower edge 40 ot casing 11 registering with the mark 39, the bar 20 will then be in its rotatable position but lower than its maximum upper position by Ahighest grooves,

a distance equa-ly to the pitch of the grooves, ,their-.bar isv rotated until the crayon holder 'd'isengages from strip 16 .and engages with grooves in innerltube, it will then be engaged with a lowerzset of grooves than before, the outer casing with bar is then drawn upto its maXimum upper position and the bar again rotated to re-engage the crayon holder witlithe strip 1.6 in a corresponding vlower set .of grooves, outer `casing 11. is then pushed down, projecting crayon through .nozzle `readyrfor use as before described.

This operation .may-be. repeated until crayon is exhausted, thel crayon holder will by that time bewvorliing in the lowest of the grooves, and niustbe restored to the upper grooves,

and. a new .Crayon inserted.- To reduce amount of crayon projected through nozzle opening, `the crayon Aholder must be `shifted yto engage with higher grooves, Vthe outer casing and bar with crayon holder engaged with strip 16, being4 Iii-st set at its maximum -upper position, bar 2O is then rotated to dis- .engage crayon holder from strip '16, then outer casing' is set with its lower edge 4l() :registering with the mark 39. on inner tube, the bar 20 is then rotated to re-eiigage crayon holder with strip 1 6 then outer casing ll is pushed down, Hprojecting the crayon vthrough nozzle a shorter distance than be- .,foie, .this may be repeated as often aS. necessary until .crayon holder is working in the n. mient` i sectionai rieivs oa modified `form, of inner tube l2 and nozzle 13b are shown in Figures l1 and 12, which .may be used if desired to 'make the nozzleend of {pencilrappear outwardlyvlmore equally centered than before described. VFigure 11 shows a cross section. of inner tube l2, with its inner 'circumference andv its outer cir- Vcuniferenee.in. eccentric relation to each other. Thetliicker part may be hollow to reduce-weight and alsoto vprovide amaga zine,V il Jfor reserve crayons. The strip 16 is madethiclier to correspond with the extra" thickness of slot 19. The flange. 23 is shaped eccentrically toconform to the shape of the niodiiied 'forniof inner tube l2 the flange 22 on bar 20y and cap- 2li' are assembled Atherewith `aspreviously described.
